“…However, the new solutions could be unsuitable for the current problem and consequently lead to non-guaranteed adaptation timeliness, as shown in Table 13. On the contrary, Anda and Amyot [73,74] have used a goal reasoning method (without constraints or conditions on its choices) to generate on the fly the best solutions when unforeseen circumstances are encountered at runtime. Since the used mathematical functions include the impact of the current environmental condition on all elements of the goal models and are restricted by the mathematical function of feature models, the created solutions are feasible and the best (the functionality and quality of the system satisfy its stakeholders' objectives) for the current environmental condition.…”

“…This language was used to keep tracking and using the goal model from requirements elicitation to the implementation phase. Anda and Amyot [31,73,74] generate arithmetic functions in common languages (including C, Java, and Python) from GRL and feature models, which enable analysis and implementation to be done with a wide range of development tools.…”

“…The last model was integrated with the Consol-Optcad optimization tool for early cost and performance estimation. Anda and Amyot [31,73,74], Anda [75] Transformed GRL and feature models into mathematical functions that can be executed outside of goal modeling tools including SysML, simulation, optimization, and implementation tools. Also, goal and SysML models are imported into an RMS to manage traceability and consistency as models evolve.…”

“…However, these analyses are limited to static decisions and adaptions, often outside of the SysML model as well. To support goal-based design selection and runtime adaption in a way that is integrated with SysML, Anda and Amyot [73][74][75]78] generate arithmetic functions from GRL models that can be inserted in SysML models for simulation and optimization, and in the system code for runtime adaptations. Method Realization As seen in Table 7, all but four studies used some level of SysML profiling to map goal concepts to SysML concepts (often using requirements diagrams as a basis).…”

“…She used stored cases and patterns only while the feedback technique was not applied, in order to continue enhancing the stored cases, as Qian et al [94] did. To enhance overall system performance, new strategies or configurations can be issued by the optimization method of Anda and Amyot [31,73], which deals with unexpected conditions at runtime.…”

Background: Socio-cyber-physical systems (SCPSs) are a type of cyber-physical systems with social concerns. Many SCPSs, such as smart homes, must be able to adapt to reach an optimal symbiosis with users and their contexts. The Systems Modeling Language (SysML) is frequently used to specify ordinary CPSs, whereas goal modeling is a requirements engineering approach used to describe and reason about social concerns. Objective: This paper aims to assess existing modeling techniques that support adaptation in SCPSs, and in particular those that integrate SysML with goal modeling. Method: A systematic literature review presents the main contributions of 52 English articles selected from five databases that use both SysML and goal models (17 techniques), SysML models only (11 techniques), or goal models only (8 techniques) for analysis and self-adaptation. Result: Existing techniques have provided increasingly better modeling support for adaptation in a SCPS context, but overall analysis support remains weak. The techniques that combine SysML and goal modeling offer interesting benefits by tracing goals to SysML (requirements) diagrams and influencing the generation of predefined adaptation strategies for expected contexts, but few target adaptation explicitly and most still suffer from a partial coverage of important goal modeling concepts and of traceability management issues.

A paradox of requirements specifications as dominantly practiced in the industry is that they often claim to be object-oriented (OO) but largely rely on procedural (non-OO) techniques. Use cases and user stories describe functional flows, not object types. To gain the benefits provided by object technology (such as extendibility, reusability, and reliability), requirements should instead take advantage of the same data abstraction concepts -classes, inheritance, information hidingas OO design and OO programs.Many people find use cases and user stories appealing because of the simplicity and practicality of the concepts. Can we reconcile requirements with object-oriented principles and get the best of both worlds?This article proposes a unified framework. It shows that the concept of class is general enough to describe not only "object" in a narrow sense but also scenarios such as use cases and user stories and other important artifacts such as test cases and oracles.Having a single framework opens the way to requirements that enjoy the benefits of both approaches: like use cases and user stories, they reflect the practical views of stakeholders; like object-oriented requirements, they lend themselves to evolution and reuse.
